 * @brief  Grammar file list management on startup.
 *
 * These functions are for managing list of grammar files to be loaded
 * at startup.  You can also specify (list of) grammars to be included
 * for recognition at startup by calling these functions.  If you want to
 * add, modify or remove grammars while recognition, you should prepare
 * grammar data and call functions in multi-gram.c directly.
 * @sa julius/module.c for the implementation details.
